NPC Summons

Scholar of the First Sin: Bashful Ray. Small white sign. In the first open domed hut after the Bridge Approach bonfire, near the corpse with the Morning Star. Considering the distance to the boss fog, it may be wise to clear the path before summoning him. His pyromancies and rapid attacks can make quick work of the boss.

Scholar of the First Sin: Creighton the Wanderer. Found next to the portcullis in the cave next to the Undead Lockaway bonfire.

Strategy

This boss exhibits strength in numbers. If you're not careful, the sheer amount of enemies on the field can overwhelm you.

You first face off against the Lords themselves, who use pyromancies and melee attacks. They take a long time to actually start attacking you, so use this to your advantage to get in one or two hits on them. Use the mounds of skeletons as cover.

Each Skeleton Lord spawns a different type of smaller skeleton when killed:

Sorcery

Use the bone pillars as cover. Then, once you've got some space, attack the Lords with your spells or heal as needed.

Once the smaller skeletons spawn quickly switch to Yearn and cast it somewhere across the room. The skeletons will ignore you while it's active. This will give you time to finish them off one by one. If you are slow to cast it you might have to dodge one or two Bonewheel Skeletons before they are distracted.

You probably won't be able finish them all before the spell wears off. Yearn makes a noise while it's active. Once you hear it stop, quickly cast it again.

If you have trouble with the NG+ skeleton wheels, use the hex Darkstorm. Simply use it as soon as they start to appear or charge you, and they will be one-shot without a chance of hitting you.

Miracle

Equip Heavenly Thunder and stand in water to draw the skeletons around you, the area of effect of each pillar will mostly kill one or more skeleton each strikes.

Use the default mace or a lightning infused mace to deal with the bonewheel skeleton as they spawn as they are quick and will deal a huge amount of damage if not blocked or dodged.

The Mace is great to backstab the skeleton lords themselves dealing a huge chunk of their health if not killing them outright. Don't try to crowd control with the mace as it's reach is ridiculous.
